PRETORIA, South Africa -- A South African prosecutor has charged Olympian Oscar Pistorius with the premeditated murder of his model girlfriend.

The prosecutor said Tuesday that Pistorius shot 29-year-old Reeva Steenkamp four times through the bathroom door of his home in a guarded and gated complex in the South African capital, Pretoria. Prosecutor Gerrie Nel told the court the door had been broken open.

Police arrived at Pistorius' home in the early hours of Valentine's Day and found the body of 29-year-old Reeva Steenkamp with four bullet wounds. They were responding to neighbors' calls about shouting and gunshots. A 9 mm pistol was recovered.
